Natural forms · Metals: 26 3D models
Every element as an atom, orbitals and bonding, crystals, ions and complexes, real compounds from every field of chemistry, substances in their natural form, electrochemistry and lab experiments (real sizes atoms → lab bench). Each one is a ready-made 3D model you can turn, recolour and place in a figure — open BioDioRama and type its name in the Library search.
- Sodium metal under oil — Sodium is a soft, silvery metal that tarnishes in seconds and reacts violently with water, so it is stored under mineral oil. (Na) (≈ 5–20 cm (a lab sample))
- Potassium metal under oil — Even more reactive than sodium: potassium is kept under oil and bursts into a lilac flame on water. (K) (≈ 5–20 cm (a lab sample))
- Lithium metal under oil — The lightest metal — it floats on the oil it is stored in. The anode metal of lithium batteries. (Li) (≈ 5–20 cm (a lab sample))
- Calcium metal granules — Dull grey-white granules of calcium metal, which fizz steadily in water. (Ca) (≈ 5–20 cm (a lab sample))
- Magnesium ribbon — A coil of magnesium ribbon — it burns with a dazzling white flame to magnesium oxide. (Mg) (≈ 5–20 cm (a lab sample))
- Aluminium foil — Aluminium rolled thin into foil; a thin oxide layer protects it from corrosion. (Al) (≈ 5–20 cm (a lab sample))
- Iron filings — Fine iron filings — attracted by magnets and used to show magnetic field lines. (Fe) (≈ 5–20 cm (a lab sample))
- Copper wire coil — Copper is reddish, soft and an excellent electrical conductor — hence wires. (Cu) (≈ 5–20 cm (a lab sample))
- Native copper (dendritic) — Copper as it is found in nature: branching (dendritic) crystals of the pure metal. (Cu) (≈ 5–20 cm (a lab sample))
- Granulated zinc — Lumpy zinc granules — they react with dilute acids to give hydrogen. (Zn) (≈ 5–20 cm (a lab sample))
- Lead shot — Dull grey, very dense lead pellets. (Pb) (≈ 5–20 cm (a lab sample))
- Tin granules — Shiny tin granules; tin plates steel cans and makes solder and bronze. (Sn) (≈ 5–20 cm (a lab sample))
- Gold bar — A gold ingot: dense, soft, yellow and untarnished — gold does not react with air or water. (Au) (≈ 5–20 cm (a lab sample))
- Gold nugget — Native gold as found in rivers: a rounded nugget of nearly pure metal. (Au) (≈ 5–20 cm (a lab sample))
- Silver bar — A silver ingot — the best electrical and thermal conductor of all metals. (Ag) (≈ 5–20 cm (a lab sample))
- Platinum cube — Platinum: a dense, unreactive, silvery metal used in catalytic converters and electrodes. (Pt) (≈ 5–20 cm (a lab sample))
- Titanium sponge — Porous titanium "sponge" straight from the Kroll process, before it is melted into metal. (Ti) (≈ 5–20 cm (a lab sample))
- Tungsten cube — Tungsten has the highest melting point of any metal (3422 °C) and is almost as dense as gold. (W) (≈ 5–20 cm (a lab sample))
- Mercury — The only metal that is liquid at room temperature: heavy, silvery beads of mercury. (Hg) (≈ 5–20 cm (a lab sample))
- Gallium (melting crystal) — Gallium melts at 29.8 °C — it melts in your hand. (Ga) (≈ 5–20 cm (a lab sample))
- Bismuth crystal (hopper) — Bismuth grows stepped "hopper" crystals whose thin oxide film shines in rainbow colours. (Bi) (≈ 5–20 cm (a lab sample))
- Chromium pieces — Hard, bright, bluish-silver chromium — the shine of chrome plating. (Cr) (≈ 5–20 cm (a lab sample))
- Nickel pellets — Slightly golden-grey nickel pellets; nickel is magnetic and resists corrosion. (Ni) (≈ 5–20 cm (a lab sample))
- Cobalt pieces — Hard, bluish-grey cobalt metal — used in magnets, superalloys and battery cathodes. (Co) (≈ 5–20 cm (a lab sample))
- Osmium (densest element) — Bluish-grey osmium is the densest natural element (22.6 g/cm³). (Os) (≈ 5–20 cm (a lab sample))
- Uranium metal (oxidised) — Uranium metal darkens quickly in air as it oxidises; it is weakly radioactive. (U) (≈ 5–20 cm (a lab sample))
